Product Description:

The PRS-3921B is a servo drive board. It is a useful product by Sanyo Denki from the PRS Servo Drive Boards series that is particularly designed for industrial control setups. It can handle around 200 to 240 volts of operational voltage. A current usage of 2 amp to 5 amp is also a necessary feature . It is said to being compatible with most automation systems. It has a digital servo drive system and can provide accurate position, speed, and torque control to provide smooth and timely functioning.

Being coupled with RS-485 and TCP/IP communication ports, it easily integrates with industrial networks as well as distant monitoring platforms. It provides high-resolution feedback at an accuracy level of almost 0.1° with reference to accurate measurements, suiting application which requires accurate motion control. For the purpose of serving a faster response, it has superior dynamic performance that gives lower latency on even high-critical operations. Overload protection, overheat protection, and short circuit protection are in-built to provide protection against system failure and extend operating life. Fan-cooled or force air technology-based cooling system avoids overheating and provides consistent performance during taxing situations. Industrial-grade engineered, it offers stable performance around 55°C temperature with reliability across various conditions.

Due to the miniature size and universal mounting dimension, simple installation in new and already installed systems is feasible. As an industrially designed, light-weight structure, it ensures efficiency along with ruggedness. Being a manufacturing automation, robot, or high-speed processing solution, the PRS-3921B offers stable and reliable performance. With its state-of-the-art technology, it is an economical choice for engineers looking for a universal and reliable servo drive solution. Blending high accuracy, intelligent connectivity, and strong security, the model easily deals with the modern demands of industrial automation.
